Moraes, Amaury Cesar;
Tempo Social , 2003, DOI: 10.1590/S0103-20702003000100001
Abstract: a short summary of the central questions regarding the teaching of sociology in brazilian secondary schools: the intermittent character of the teaching, the fragmentation of the researches, the difficulties in the consolidation of minimum contents and didactic materials. based on a recent bibliography and on my own experience as professor of teaching methodology of social sciences, i relate these difficulties, on the one hand, to the distance and hierarchization that exist between the social scientists as academic intellectuals and the social scientists as secondary teachers and, on the other, to the divorce and unbalance existing between the educational development of bachelors in social science and those taking diploma in education within the model in effect since the faculties of philosophy, sciences and letters were created in the 1930' s.

Abstract: Este trabalho aborda a rela o entre a escola e os recursos audiovisuais utilizados por ela, destacando-se entre estes o cinema. A premissa é a de que mesmo as escolas estando cada vez mais equipadas, a inser o do cinema no cotidiano escolar, efetivamente, n o se realiza. Com o avan o tecnológico e o aperfei oamento dos equipamentos audiovisuais, hoje, a grande maioria da popula o tem acesso às grandes produ es cinematográficas através de fitas de videocassete e DVD. Tal crescimento parece ser ignorado pela educa o escolar, e as administra es públicas divulgam largamente o fato de equiparem as escolas para a reprodu o de filmes, mas sem uma preocupa o paralela de forma o e capacita o dos professores para tal empreendimento. Este trabalho também tece reflex es sobre a importancia histórica da linguagem do cinema e de seu caráter de conhecimento historicamente acumulado a ser transmitido pela escola aos que a ela chegam. As hipóteses deste projeto – de que a linguagem do cinema, além de ser um instrumento pedagógico (recurso didático), também é um objeto de conhecimento que possibilita a percep o da realidade mais ampla, e de que os cursos de forma o de professores n o os preparam para uma adequada utiliza o deste recurso e para a apropria o desta linguagem – foram, durante a trajetória teórica e empírica, confirmadas, o que comprova que a escola ainda faz uma utiliza o fragmentada, inadequada e incipiente das novas linguagens, tecnologias e saberes; obtendo, conseqüentemente, resultados muito aquém dos que poderia atingir através de uma apropria o efetiva dessas linguagens, tecnologias e saberes. Palavras-chave: Educa o. Cinema. Forma o de professores.
Ensino de Sociologia: periodiza??o e campanha pela obrigatoriedade
Moraes, Amaury;

Abstract: although the chronologies reports as a result of an objectivity of dates, such dates are marked by a choice and that choice is an indication of interpretation. the dates are far from indisputable data - are also constructed, as historical facts, are part of a release. in the case of sociology, the current interpretation of its presence/absence in high school should be a marked ideological context: in democratic periods, sociology is present, at times authoritarian, sociology is absent. our hypothesis is that this interpretation derives from the perspective of those who are in favor of enforcing discipline; they say that sociology, by being critical, is a threat to the regime and is deleted. for us, other factors that conditioned this intermittence, especially the formation of an educational bureaucracy responsible for managing the curriculum.

Abstract: The effects of cutting plant age (21, 28, 35, 42, 49, 56, 63 and 70 days) on dry matter (DM) yield, and radiation use efficiency (RUE) of Axonopus aureus, during dry season, were evaluated under natural field conditions. DM yields, absolute growth rate (AGR), crop growth and relative growth rates and leaf area increased consistently with growth stage. The relations between DM yield and AGR with cutting plants age were described by the quadratic regression model. The maximum DM yield, AGR and RUE were estimated at 62.6; 47.8 and 51.7 days of regrowth, respectively. The response of forage yield to incident photosynthetically active radiation was quadratic and maximum value estimated at 487.7 MJ/m2, which corresponded to 796.7 kg of DM/ha. These data suggest that cutting at 49 to 56 days were optimal for obtain maximum dry matter yields and improved the incident RUE.ResumoO efeito da idade de rebrota (21, 28, 35, 42, 49, 56, 63 e 70 dias) sobre a produtividade de matéria seca (MS) e a eficiência de utiliza o da radia o (EUR) de Axonopus aureus, durante o período seco, foi avaliado em condi es de campo. O aumento da idade de rebrota resultou em maiores rendimentos de forragem, taxa absoluta de crescimento, taxa de crescimento da cultura, taxa de crescimento relativo e área foliar. As rela es entre idade de rebrota, rendimento de MS, taxa absoluta de crescimento e EUR foram ajustadas ao modelo quadrático de regress o, sendo os máximos valores registrados aos 62,6; 47,8 e 51,7 dias de rebrota, respectivamente. A resposta da produtividade de forragem à RFA incidente foi quadrática e o máximovalor estimado em 487,7 MJ/m2, o qual correspondeu a 796,7 kg de MS/ha. Visando conciliar produtividade de forragem da gramínea com a maximiza o da EUR, o período de utiliza o mais adequado de suas pastagens situa-se entre 49 e 56 dias de rebrota.

Abstract: The effects of regrowth age (21, 28, 35, 42, 49, 56, 63 and 70 days) on dry matter (DM) yield, and morphogenetic and structural characteristics of Axonopus aureus, submitted to burning, during dry season, were evaluated under natural field conditions. Evaluations were carried out during the period of December 2010 to February 2011. DM yields, absolute growth rate, number of tillers/plant, number of leafs/plant, leaf area, leaf senescence and elongation rates and blade length increased consistently with growth stage. The relations between DM yield and forage production rate with cutting plants age was described by the quadratic regression model. The maximum DM yield and forage production rate performance were estimated at 69.14 and 45.49 days of regrowth. The crop growth and relative growth rates, tiller and leaf appearance rates were inversely proportional to cutting plant age. To maximize the forage use efficiency and to prevent larger losses relative to senescence and leaves death, it is recommended a regrowth interval between 42 to 56 days. = O efeito da idade de rebrota (21, 28, 35, 42, 49, 56, 63 e 70 dias) sobre o rendimento de forragem e características morfogênicas e estruturais de Axonopus aureus, submetido a queima, durante o período seco, foi avaliado em condi es de campo. As avalia es foram realizadas no período de dezembro de 2010 a fevereiro de 2011. O aumento da idade de rebrota resultou em maiores rendimentos de forragem, taxa absoluta de crescimento, número de perfilhos/planta, número de folhas/perfilho, tamanho médio de folhas, área foliar e taxas de expans o e senescência foliar.

As taxas de crescimento da cultura, taxa de crescimento relativo, taxas de aparecimento de perfilhos e de folhas foram inversamente proporcionais às idades de rebrota. Visando maximizar a eficiência do uso da forragem produzida e reduzir as perdas por senescência foliar de Axonopus aureus, o período de utiliza o mais adequado de suas pastagens, durante o período seco, situa-se entre 42 e 56 dias de rebrota.
Bovine Bone Charcoal as Support Material for Immobilization of Bacillus firmus Strain 37 and Production of Cyclomaltodextrin Glucanotransferase by Batch Fermentation in a Fluidized Bed  [PDF]
Larissa Albunio Silva, Bruno Cesar Bieli, Osvaldo Valarini Junior, Graciette Matioli, Gisella Maria Zanin, Flavio Faria Moraes
Advances in Chemical Engineering and Science (ACES) , 2018, DOI: 10.4236/aces.2018.81002
Abstract:
The process described in the present work uses air supplementation in a fluidized bed reactor containing Bacillus firmus strain 37 immobilized on active bovine bone charcoal, to produce by batch fermentation the enzyme CGTase (cyclomaltodextrin-glucanotransferase). Three different aeration rates were evaluated. The maximum CGTase activity was achieved after 120 hours of fermentation with aeration rate of 2 vvm and was equal to 2.48 U/mL. When 0.5 and 1 vvm were used the enzymatic activities achieved 1.1 and 0.57 U/mL, respectively. Bovine bone charcoal was characterized in terms of surface area, pore size and volume. To the best of our knowledge, the immobilization of microorganism cells in bovine bone charcoal for CGTase production has not been reported in the literature. Our results showed that fluidized bed reactor allows retaining high concentration of biomass, improving biomass-substrate contact and operation at low residence times, which resulted in improved enzyme production. Therefore, the process as proposed has great potential for industrial development.
A Simple Remark Leading to a Basic Precision Estimate for Non-Relativistic (NR) Real Values of Quantum Mechanics Operators  [PDF]

Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.64071
Abstract: Starting with a very basic statement that any physical constants cannot be written with an infinite precision, it is shown how to introduce this uncertainty into the Hamiltonian of non-relativistic atomic (NR) physics and how to estimate errors on quantum operators (energy, frequency, momenta) when an uncertainty \"\" is assigned to \"\". The Schrödinger equation is written and the kinetic energy term \"\" is transformed into a Laplacian: \"\". This transformation leads (as known since 1926) to the wave equation, whose solutions are wave functions. The relativity correction to the kinetic energy term is introduced and its effect is discussed. (h constant has an uncertainty \"\" value taken from CODATA.)
